Enhancement: HTML report

[ayushnirwal]

Description

• Remove blocked cookie categories from the HTML report when exported from the extension.
• Add a header component to the report that shows the URL that was analyzed. This is only done from a report of single-page analysis since CLI does not supply the sitemap's URL to the sitemap dashboard.

Testing Instructions

• Reports exported from the extension -
  a) Should have a header displaying the URL of the page analyzed.
  b) Should not have a section for categories of blocked cookies.
• Reports exported from CLI dashboard (Single Page) -
  a) Should have a header displaying the URL of the page analyzed.
• Reports exported from CLI dashboard (Multipage Page) -
  a) Should have a header displaying the URL of the page analyzed in the report for every website.
  b) Composite report ( report.html in the root folder ) should not have the header.
